Definitions
- the invention relates to a device for sucking up particles to be collected, with at least one collecting chamber for collecting the particles and at least one receiving chamber for suction means, the collecting chamber and the receiving chamber being separated from one another by a partition wall which forms an inlet opening for an air flow from the collecting chamber to the suction means having.
- Canister vacuum cleaners whose suction power is too low. This can result, for example, from an angled guidance of the suction air flow through the extremely compact arrangement of the individual components inside the housing of such vacuum cleaners. Furthermore, due to the limited space available, often only less powerful blower units or suction units can be installed in the chassis of such a vacuum cleaner, which have lower suction power than conventional, larger types of vacuum cleaner.
- the invention has for its object to provide a device for sucking up particles to be collected, the suction power is improved even with a compact design.
- This object is achieved in a device of the type mentioned at the outset in that the partition has an air guide funnel as an inlet opening for coupling the collecting chamber to the suction means of the receiving chamber, the inlet surface of which forms the essential part of the partition wall surface.
- the partition wall has an air guide funnel as the inlet opening, the inlet surface of which forms the essential part of the partition wall surface, an excessive pressure loss of the air flow from the collecting space or the collecting chamber to the suction means is largely avoided. This also largely avoids excessive noise. Because the bigger the partition wall has an air guide funnel as the inlet opening, the inlet surface of which forms the essential part of the partition wall surface, an excessive pressure loss of the air flow from the collecting space or the collecting chamber to the suction means is largely avoided. This also largely avoids excessive noise.

- the invention further relates to a vacuum cleaner, in particular a vacuum cleaner, which is designed according to the principle of the invention.
- Figure 1 is a schematic cross-sectional view in plan view of the essential components of a vacuum cleaner according to the invention
- Figure 2 in a schematic, spatial representation of the partition between the
- FIG. 3 shows a schematic side view of the arrangement of the functional components of the vacuum cleaner according to FIG. 1,
- Vacuum cleaner according to Figure 3 whose air guide funnel at the entrance of its suction
- FIG. 5 shows a schematic representation of the individual components of the vacuum cleaner according to FIG. 1 in the disassembled state. Elements with the same function and mode of operation are provided with the same reference numerals in FIGS. 1 and 5.
- FIG. 1 shows schematically in plan view the arrangement of the essential components of a vacuum cleaner SS, which is designed according to the principle of the invention. It has an inlet opening EO on the one end face of its housing GH with a preferably circular cross section for sucking in suction air SL.
- a first collecting chamber or a collecting space SR is provided in the housing behind this inlet opening EO and serves to collect particles or particles to be sucked in, in particular dirt particles or dust particles.
- a filter bag or dust bag PF is used in the collecting space SR to receive the dirt or dust particles ST sucked into the collecting chamber SR from the outside through the inlet opening EO.
- the filter bag PF is attached to the inside of the outlet end of the approximately tubular inlet opening EO, so that particles or particles sucked in from the outside get directly into the interior of the dust bag PF.
- At the entrance opening EO is usually an outside
- At least one filter element such as a filter fleece, in the collecting chamber SR between the inlet opening EO and the dust bag PF.
- a receiving chamber MR is separated from the collecting space or from the collecting or dust chamber SR by an intermediate wall TW.
- This receiving space MR is used, in particular, for the accommodation and storage of suction means with which a directional suction air flow LF can be generated through the inlet opening EO, the collecting space SR and the dust bag PF provided there, if necessary.
- the routing of the air flow LF through the interior of the housing of the vacuum cleaner SS is indicated by dashed arrows.
- the suction means are primarily formed by a blower GB of a known type, which is driven by a motor MO.
- the rotor blades of the blower GB are designed in such a way that they suck air from outside through the inlet opening EO into the interior of the housing GH, through the collecting space Allow SR to flow through, then extract through an inlet opening in the partition TW into the receiving space MR, and finally blow out again through outlet openings AO in the housing GH.
- the outflowing blow-out air is also indicated in FIG. 1 with dashed arrows AL.
- other components of the vacuum cleaner such as its cable drum KT for winding up an electrical connecting cable KA, can also be accommodated in the receiving space MR.
- the inlet opening in the partition TW is expediently provided at such a point that the air flow LF from the inlet opening EO through the collecting space SR to the suction means GB, MO behind the Partition TW can be guided in a substantially rectilinear manner in the receiving space MR.
- the inlet opening in the partition wall TW is designed as an air guide funnel LT.
- Air guide funnel LT tapers from its entry surface at the collecting space SR towards the suction means GB, MR.
- the suction means, in particular the blower GB, are mechanically coupled as closely as possible to its outlet opening.
- FIG. 2 An expedient embodiment of the air guide funnel LT from FIG. 1 is shown in detail in FIG. 2 in a spatial representation.
- the air guide funnel LT has an essentially rectangular entry surface RE for the air flow LF from the dust space SR.
- the entry surface RE of the air guide funnel LT is essentially flush with the otherwise preferably planar partition TW.
- the inner walls of the air guide funnel LT then converge towards one another in the manner of a cone in the direction of the suction means which are located behind the partition wall TW.
- the inner walls of the air guide funnel LT finally form an outlet opening which is approximately circular in cross section for the positive coupling of the approximately circular outlet pipe of the blower GB.
- This form of the air guide funnel LT as a coupling component for the air flow LF between the collection chamber SR and the receiving chamber MR is shown enlarged in a cross-sectional view in FIG. 4 in a side view.
- the interior of the air guide funnel LT ends with an approximately circular outlet opening KRO.
- the blower GB mechanically coupled.
- the impellers LR of the blower GB are guided on the end face in the sealing element GT, where they grind themselves in tightly through operation.
- a buffer is formed between the respective impeller such as LR and the outer housing of the blower GB by the sealing element GT.
- the air guide funnel LT is now advantageously designed as an inlet opening in the partition wall TW such that its inlet surface forms the essential part of the partition wall surface. This can be seen particularly in FIG. 2.
- the inlet area RE of the air guide funnel LT preferably takes at least 50%, preferably between 70 and 80%, of the
- the air guide funnel causes a homogeneous transition for the air flow LF from the collection chamber SR to the suction means coupled to the outlet opening of the air guide funnel LT due to its shape tapering in the direction of the suction means GB, MR.
- the suction tube AR of the suction means GB, MR preferably has a circular cross section that is significantly smaller than the cross sectional width of the partition wall TW.
- the approximately conical tapering of the air guide funnel LT causes an additional suction effect for the air flow LF from the collecting chamber SR through the partition wall TW into the receiving space MR.
- the widening inlet channel of the air guide funnel LT which widens in the direction of the collecting chamber SR, additionally achieves a bundling effect or focusing of the air flow LF.
- the air flow LF can be directed in a targeted manner through the receiving chamber SR and the dust bag PF introduced there, that is to say a route for the air flow can be specified.
- the air flow LF is guided essentially in a straight line by appropriately aligning the inlet opening of the light guide funnel LT with the opposite inlet opening EO of the collecting chamber SR.
- an anti-tamper element ES projecting in the direction of the collecting chamber SR in the base, that is to say in the vicinity of the outlet opening of the air guide funnel LT.
- This is preferably conically curved.
- it has a rib body with gaps for the passage of the air flow LF.
- This rib body is oriented in the opposite direction to the tapering of the inlet duct of the air guide funnel LT.
- it also has a funnel shape that widens in the direction of the collecting chamber SR. This also makes it possible to increase the entry area for the air flow LF.
- An undesirable loss of pressure in the air flow LF during the transition from the collecting chamber SR to the suction means GB, MO is thus largely avoided.
- This rib-shaped engagement protection element ES prevents the operator from entering the blower inadmissibly, so that, for example, hand injuries caused by the rotating blower blades are largely avoided. Thanks to the special funnel shape of the motor protection grille
- the anti-tamper element ES can advantageously have the free air cross-section between the individual ribs as large as possible, and thus a relatively small obstruction of the air flow can be achieved despite this additional protective measure.
- rib bodies of different shape can also possibly also fulfill a safety function.
- the dome-like tamper protection element ES expediently protrudes from the collection chamber SR only to such an extent that its outer contour is flush with the entry surface RE of the air guide funnel LT.
- At least one filter element FI can advantageously also be attached in front of the inlet opening of the air guide funnel LT by means of two web clamps SU, SI2 arranged laterally from the entry surface RE of the air guide funnel LT.
- This filter element FI is used for further cleaning of the exhaust air LF, which is drawn off from the dust chamber SR. It can be designed in particular as a pollen or allergy filter.
- One or more filter fleeces FIV are preferably clamped there between the two halves of a booklet-like holding grid HF. This is shown in Figure 5, where the other components of the vacuum cleaner are shown in a disassembled state.
- partition TW the partition TW, the air guide funnel LT, and / or its front engagement protection element ES as a one-piece component.
- the air guide funnel can thus be firmly, that is to say integrated directly into the plastic housing of the partition between the dust chamber and the engine compartment.
- the engine or the associated blower is then expediently coupled and sealed via rubber parts to the outlet opening of the air guide funnel.
- the air guide funnel can optionally be inserted as an additional part on the engine or the fan cover.
- the entire unit is then coupled and sealed in the device body via known rubber parts.
- the suction air could only get into the blower from the dust chamber by very large bends.
- the air is now guided from the dust chamber into the fan in a streamlined manner through the air guide funnel.
- This air guide funnel is advantageously designed as a rectangle in the dust space to enlarge the entry area.
- the funnel shape preferably runs quickly and without a contour jump to the round diameter of the fan inlet opening.
- protective ribs can be attached in the middle of the funnel (opening to the fan).
- the rib body is expediently designed to be funnel-shaped in the opposite direction to the air guide funnel in the direction of the dust chamber.
- This special funnel shape of the motor protection grille (rib body) allows the free air cross-section between the individual Ribs are made as large as possible or a relatively less obstruction of the air flow can be achieved. This enables an overall increase in the air output and thus an increase in the output of the respective vacuum cleaner.
